Winter wheat how to freeze

In the appropriate period of high-quality sowing, strive to achieve the basis of Qi, uniform, all based on the promotion of weak control, to achieve a suitable group, the individual robust, and coordinate the growth of seedlings and nutrient storage relationship, to ensure safe winter wheat seedlings. Winter freezing of wheat mainly has the following four points:
Cover grass. Before winter, in the wheat row, 300-400 kilograms of wheat bran, wheat straw, or other plant wastes are spread per acre, which guarantees both picking up and freezing. After the decay, the soil can be improved and fertility can be cultivated. This is wheat's drought resistance and antifreeze. Increased production of effective measures.
The soil is surrounded by roots. When the wheat seedlings are about to stop growing before the winter, the combination of ploughing and ramming soil can effectively prevent the winter wheat from freezing. The year of serious frost damage is particularly obvious, and the yield can generally increase by 5% to 10%.
Cover dung. After winter wheat enters the wintering period, a layer of manure (commonly known as “warm ditch manure”) is spread on the ridges to protect the wind, protect the soil, increase the temperature and prevent freezing, and supplement the nutrients for the young seedlings. The thickness of the manure is preferably 3-4 cm. The application of manure is about 5 cars per acre, but when it is insufficient, late barley fields, shallow-seeding wheat fields, sandy wheat fields, and wheat fields sown with weak winter varieties are preferred.
Spray Chestnut. In the winter when the wheat is frost-damaged, spray the wheat seedlings with 0.3%-0.5% chlorcholine solution to inhibit the growth of the plants and resist or reduce the occurrence of frost damage.
